This paper describes the process of developing graphical metaphors and diagrammatic
representations for the Human Development Index – HDI– and its components: the HDI
Tree (UNDP, 2011). In 1990, the United Nations Development Programme introduced the
Human Development Index as a measure of development that combines indicators of life
expectancy, educational attainment and income. The project was commissioned to César A.
Hidalgo (2010) by the Human Development Report office and developed in collaboration
with three senior students at Northeastern University. The objective was to explore ways to
simplify and communicate the Human Development Index using visual rather than numerical
representations. Here, we describe the design process, discuss the concepts behind the metaphor,
and analyze two selected visualizations. We conclude by examining how the Development Tree
can be used in visual narratives for educational and outreach purposes.
